Lifan has been adjusting its parts.
Older models of Lifan suggest either running the tank empty or draining all gas should ethanol blend be used. This did not have a petcock
The newer models do not suggest this... and the tech is to look for ''ethanol etch'' within the float bowl to determine warranty certification.
''Ethanol etch'' is the result of not shutting off the petcock and running the carb dry as recommended. Raw gas will do the same thing...
All the manufacturers have been getting ready for more ethanol in the motors since President Trump first tried to change to E15 on summer blend by EO several years ago.
